CATTLE-STNCHION.

SPECIPIGATION' forming part of Letters Patent N0. 342,389, dated May25, 1886.

Applicntion filed Feb1nmy 1, 1886. Soviel No 190,540 (N0 model.)

Beitknown that I, NORMAN H. SANBORN, 0f Hampton, in the eonnty of Roekingham and State of New Hampshire, have invented newanduseful Improvements in Cattle-Stanehions, of whieh the following is a speeifieation.

In the accompanying drawings, in whieh similarletters of refereneeindieatelike parbs, Fignre 1 is an elevation of two sets ot stanehions embodying my invention,one sei; neing elosed and the obher open. Fig. 2 is a plan view with aportion in horizontal seetion on line y, Fig. 1. Fig. 3 is a vertiealseetion on line x, Fig. l.

A and B are respeetively the npper and lower horizontal bea1ns, in which the stanehions are snpported. G Gare the posts er pillars foreonfining the head. ofthe animal, eaeh pivoted ab a to the horizontal b&l d, whieh is pivoted to the beam B by 1neans of the pivol: Z), so as to be eapable of eomplebe rotaion horizontally. lhe ehamher E, in whieh the pivot b rests,is madein Widl;h of about; the thiekness of the pivot, hut in lengthextends back snfficiently to aeconnnodate the spiral spring F, as shown in Fig. 3. Tims in will be seen lzhal; the stanehion will yield somewhat to pressure or blows npon ib by the animalas, I'or example, when he is rising, ehanging position,or entering the stanehionbhns rendering the same less liable to breakage and lhe animal 120 injnry.

The upper ends of the poslss O am seenred loy means of the bolts (Z to the fra1ne H, said bolts extending throngh the slots 11 in oho extensions H of said frame. These slots are eut upon eireles o1 whiel1 the pivots a are the centers, so thal: the posts Oean swin oulsward into the positions shown in the 1ight band portion ot' Fig. l. W hen the stanehion is 6 in this position, in is prevenbed fro1n rotation by one of the posts O, lying betaween the guides J, seeured 110 the nnder sicle of the bea1n A.

The frame H, whieh is pivoted ab g to the beam A, is prm ided Wibh a horizontal pin,K,

passing eentrally through bhe lever L. Piv-.

otally seenred ab d 130 the opposite ends of said lever L are the hent levers o1 links N, whieh eonnect said lever L witl1 bhe bolts (l on whieh said links N are loosely plaeecl. A suitable sleeve, K, holds the lever L aba proper distanee in front ofbhe i'mme H, and similar sleeves,d, hold the links N ab proper distanees in fronb of tshe posts O.

Ahandle, P, parallel with and in fronb of the lever L, is seeured ab it-s opposite ends 130 the pivots d. The posts O areswnng apart by the partial rohation of said handle, whieh, by means of the pivots d, imparts sin1ilarrolaabion to bhe lever L, n.nd by means oF hhe hent; links N and bolts d forees apart tl1e posts, whieh are then held stationary hy the guides J. Reverse rotation of thehanclle brings the posts parallel er elosed,in whieh positon they are hold seenrely by reason of Ehe links passing hy the eenters, so thab the ends of seid links whieh are pivoted to the lever L are nol: als eqnal hcights, one being above and the other below the holts d. \Vhile in this position the staanchion is sec-nrely loeked, so that the animal is eonfined therein, bnt is eapable of rotation, and is also yielding by 1neans of the spring F, as above deseribecl.

Having thns fully (leseribed 1ny invention, whah lelaim, an(l desire ro seenre by Letters Patent, is

l. In a eattle-stanehion, the eomhination, witah the lower heam,Bhorizontal bar D, und posls C, pivotally seenred 110 Ehe latter, of the reverse bent links N, lever L, pivobally seeured to aframe, H, and t-he npper bea1n, A,

substantially as and for the purpose sei; forbh.

2. The eoxnbination of the npper andlower beams A B,the horizontal bar D, the postsC, pivotally seeured als their lower ends to said bar, tl1e links N, lever L, fran1e H, provided Wili]l lhe slotted extensions H, and bolts d, snbstanbially es and f0r the purpose deseribed.

3. In a eabtle-snanehion adapted to be 1'0- tated, theeombination ol'the npperand lower beams A B, horizontal bar D, posts O, pivotally seeured to seid bar, Lhe links N, lever L, pivoted frame H, provided With Ehe exlensions H, and the guides J, whereby the stanehion is prevented fron1 rotabion while il: is open, snhstantially as and for the pnrpose are adapbed 130 yield slightly to blows or IOO stanchion, consisting, essentially,of the follow 10 ing parts, viz: the beam B, chnmbered ab E,

and provided with a spring, F, the pivoted bar D, swingingposts C, beam A, pivoted frame H, provided with the extensions H, links N, 1ever L, handle P, am]. guides J, substantially as and for the purpose sei; forbh.
